Lignocellulosic biomass (or LC biomass) refers to plant biomass that is composed of cellulose, hemicellulose, and lignin. Biomass is increasingly recognized as a valuable commodity, since it is an alternative to petroleum for the production of biofuels and chemicals. Lignocellulosic biomass (LB) is an abundant and renewable resource from plants mainly composed of polysaccharides (cellulose and hemicelluloses) and an aromatic polymer (lignin). LB has a high potential as an alternative to fossil resources to produce second-generation biofuels and biosourced chemic … Lignocellulosic biomass consists of a variety of materials with distinctive physical and chemical characteristics. It is the non-starch based fibrous part of plant material.

In this study, BioSTEAM—an open-source platform—was leveraged for the design, simulation, and evaluation (via techno Lignocellulosic Biomass Production and Industrial Applications describes the utilization of lignocellulosic biomass for various applications. Although there have been numerous reports on lignocellulosic biomass for biofuel application, there have been very few other applications reported for lignocellulosic biomass-based chemicals and polymers. Lignocellulosic biomass has been considered a major source of biofuels production as a sustainable alternative to conventional fossil‐derived fuels (Jonsson, Alriksson, & Nilvebrant, 2013).

Lignocellulosic biomass

2019-01-14 Lignocellulosic biomass is typically nonedible plant material, including dedicated crops of wood and grass, and agro-forest residues.

It is the non-starch based fibrous part of plant material. Lignocellulose is a generic term for describing the main constituents in most plants, namely cellulose, hemicelluloses, and lignin. Lignocellulosic biomass can be converted into fuels and chemicals using thermochemical or biochemical process pathways.

Se hela listan på Lignocellulosic biomass (LCB) is globally available and sustainable feedstock containing sugar-rich platform that can be converted to biofuels and specialty products through appropriate processing. This review focuses on the efforts required for the development of sustainable and economically viable lignocellulosic biorefinery to produce carbon neutral biofuels along with the specialty 2020-07-03 · Lignocellulosic biomass has gained increasing recognition in the past decades for the production of value-added products (VAPs). Biomass feedstocks obtained from various sources, their composition, and pretreatment techniques employed for delignification into bioenergy production are discussed. Reduction of biomass particle size can modify the inherent ultrastructure of lignocellulosic biomass, increase the surface area for enzyme accessibility, reduce the degree of cellulose crystallinity, and decrease the degree of cellulose polymerization for enhanced digestibility (Kratky and Jirout, 2011). Lignocellulosic feedstocks are gaining increased popularity for novel industrial applications because of their availability and bio-renewability. Using lignocellulosic materials, especially from agricultural and forestry sectors could help reduce the over-dependence on petrochemical resources while providing a sustainable waste management alternative.
